Your app works on office Wi-Fi. Your users are on 3G.

Build for them:
1. Shrink payloads (fields, pagination, Brotli)
2. Expect drops (timeouts, backoff, offline queue)
3. Cache with ETag → 304 Not Modified

@kushmergedeck hi guys
@ontherules_1 and I are building @myTwedot

do check it out here: https://t.co/WSWwO1ghPp

OFFSET pagination gets slower on every deep page and repeats items when new rows land.

Use a cursor instead:
WHERE (created_at, id) < ($1, $2)
ORDER BY created_at DESC, id DESC

Every page stays fast and stable. #PostgreSQL

A timeout doesn't mean the charge failed. Often it succeeded and only the response got lost.

Send an Idempotency-Key with every payment request. Store it before you move money. On retry, replay the saved response.

No more double charges. #fintech #backend

Someone cloned Netflix.
Then cloned Spotify.
Then cloned Instagram.
Then cloned Airbnb.
Then cloned WhatsApp.
Then cloned TikTok.
Then cloned Amazon.

Then put the source code for all of them on GitHub. For free.

Not one app. Not ten. Over 100 open source clones of the biggest apps on Earth. With source code. With demos. With tech stacks listed.

It is called Clone-Wars. 34,555 stars on GitHub.

Built by an Indian-origin developer named Gourav Goyal. He started collecting open source clones of popular apps into one list in December 2020. In March 2021, it went from 0 to 4,000+ stars in 7 days. It was on GitHub Trending for 5 days straight. Someone posted it to Hacker News and it hit #1 on the front page.

Here is what is inside.

Netflix clones. React, TMDB API, full streaming UI.
Spotify clones. Music player, playlists, search, albums.
Instagram clones. Feed, stories, likes, comments, DMs.
WhatsApp clones. Real-time messaging, read receipts, group chats.
Airbnb clones. Search, booking, maps, payments.
Amazon clones. Products, cart, checkout, Stripe payments.
TikTok clones. Short video feed, upload, likes.
Twitter clones. Feed, follow, tweet, retweet.
Slack clones. Channels, threads, real-time chat.
Trello clones. Boards, cards, drag and drop.
YouTube clones. Video player, search, comments.
And 90+ more.

Every clone has source code, a live demo, and the tech stack listed. React, Next.js, Node, Firebase, MongoDB, GraphQL, Tailwind. Every modern stack represented.

Here is why this matters.

Coding bootcamps charge $10,000 to $20,000 to teach you how to build apps like these.

Udemy courses charge $50 to $200 each. One app at a time. One framework at a time.

This repo gives you 100+ fully built apps with source code you can read, fork, and learn from. For $0.

Here is the wildest part.

The best way to learn to build Netflix is to look at someone who already built Netflix. Not a tutorial that teaches you one feature at a time. A complete, working clone with every feature connected.

You do not learn architecture from tutorials. You learn architecture from reading real projects.

100+ apps. 100+ demos. 100+ source codes. One repo.

Bootcamp: $10,000 to $20,000. Teaches 2 to 3 projects.
Udemy: $50 to $200 per course. One project each.

Clone-Wars: $0. 100+ projects. Every big app cloned.

34,555 stars. AGPL-3.0 licensed.

Every app you use. Cloned. Open sourced. Free to learn from.

兄弟们，这些真不是玩具项目。

很多你还在交月费的软件，GitHub 上已经有人做出开源平替了。

一句话：

别只会收藏 AI 工具网站了。

真正狠的东西，很多都藏在 GitHub 里。

3. Añadir subtítulos atractivos
4. Recuadrar a los hablantes
5. Programar y publicar en redes sociales

esto es realmente una locura…

Opus 4.8 Is Insane.

❤️‍🔥Just recorded a 12-min tutorial on how | Build 3D Websites in Minutes with Al (0 Design + 0 Coding)

[Rohit @heyrohitai]

Instead of watching an hour of Netflix, watch this 2 hour hour Stanford lecture will teach you more about how LLMs like ChatGPT and Claude are built than most people working at top AI companies learn in their entire careers.

[Rohit @heyrohitai]

🚨 Anthropic just showed a 27-minute workshop on how to actually do prompts for Claude.

Taught by the people who built it.

Free. No registration. No paywall.

I've seen $300 courses that don't cover what they teach in the first 8 minutes.

Watch it and bookmark it now.
